Place graham cracker crumbs on top of brownie mix. Place skillet on outdoor grill and cook for 25-35 minutes at 300-325 degrees with the grill lid closed. Avoid opening the lid to check the brownies during this time so the heat stays inside and creates an oven effect.

Test with tooth pick, don’t over cook, but make sure the brownie is more than half way cooked. Add chocolate chips and then add mini marshmallows on top making sure not to overcrowd the pan. The marshmallows will swell up and puff during heating.

Place skillet back on grill until marshmallows are lightly brown about 3-5 minutes. The skillet will stay hot so the brownie will continue to cook. Place knife along edge to test brownie without disturbing marshmallows.

If the marshmallows do not brown fast enough on the grill you can place them under your oven broiler for 1-2 minutes (watch closely).

This dessert is best served warm and hot off the grill. Do not try to cut into pieces or you will pull all the marshmallows off. Just use a spoon and scoop out each serving. You may need to use two spoons or a knife to help scoot off the brownie mixture into serving bowls.
